Description

本発明は建物に設ける換気用ガラリに関し、建物の周囲で洪水などによる水位上昇が発生した際に、自動で閉塞することで建物内部への浸水を防止するための換気用ガラリに関する。   BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates to a ventilation gully provided in a building, and more particularly to a ventilation gully for automatically closing when a water level rises due to a flood or the like around the building to prevent water from entering the inside of the building.

台風などの暴風雨の降り込みによる浸水を防止するためのガラリとして、以下の特許文献に記載のガラリが知られている。
例えば特許文献１に記載の換気ガラリでは、一定風速以上の風が発生した際に、風の力で内外の可動羽根が触れて換気口部分を閉じて浸水防止機能を発揮するよう構成している。
また、特許文献２に記載のガラリでは、千鳥状に配列した縦羽根からなる補水構造体でもって、雨水を縦羽根で受け止めることで浸水防止機能を発揮するよう構成している。 As a gull for preventing inundation due to a storm such as a typhoon, the gull described in the following patent document is known.
For example, in the ventilation gallery described in Patent Literature 1, when a wind of a certain wind speed or more is generated, the inner and outer movable blades are touched by the force of the wind to close the ventilation port portion, thereby exhibiting a function of preventing water entry. .
Further, in the garbage described in Patent Literature 2, the water replenishment structure including the vertical blades arranged in a zigzag manner is configured to receive the rainwater by the vertical blades, thereby exhibiting the function of preventing flooding.

特開２００１−４０９５１号公報JP 2001-40951 A 特開２００１−１９３３６７号公報JP 2001-193367 A

しかし、上記した従来のガラリでは、以下に記載する構造上の問題から、洪水などの建物周辺の水位上昇に対する浸水防止機能を発揮することは出来なかった。
（１）特許文献１に記載の換気ガラリでは、水位上昇に伴う水圧でもって内外の羽根が開く方向へと付勢される場合があるため、浸水を確実に防止することができない。
（２）特許文献２に記載のガラリでは、あくまで千鳥状に配列した縦羽根でもって雨水を受け止めるだけであり、ガラリ内の通気空間を閉塞する機能を有していないため、水位上昇に伴い、当然に屋内への浸水が発生する。 However, in the above-mentioned conventional gullari, it was not possible to exhibit the function of preventing inundation against a rise in water level around the building due to a flood or the like due to a structural problem described below.
(1) In the ventilation galleries described in Patent Literature 1, since the inner and outer blades may be urged in a direction in which the inner and outer blades are opened due to a water pressure accompanying a rise in the water level, inundation cannot be reliably prevented.
(2) In the gallery described in Patent Literature 2, rainwater is merely received by the vertical blades arranged in a staggered pattern, and the gallery does not have a function of closing the ventilation space in the gallery, so that the water level rises. Naturally, indoor flooding occurs.

よって、本願発明は、洪水などの増水によって建物周辺の水位が上昇した際に、ガラリからの浸水を防止することが可能な手段の提供を目的とする。   Therefore, an object of the present invention is to provide a means capable of preventing inundation from a gull when the water level around a building rises due to an increase in water such as a flood.

上記の課題を解決すべくなされた本願発明は、増水時の水の浸入を防止するための換気用ガラリであって、換気用の通気空間を有する、固定羽根と、前記固定羽根よりも室外側に位置し、前記通気空間を閉塞するように移動可能な、可動羽根と、を少なくとも具備し、室外のガラリ周辺の水位が所定の高さに達した時に、前記可動羽根が前記通気空間を閉塞するように動作することを特徴とする。
また、本願発明は、前記可動羽根が受ける水の水圧でもって、前記可動羽根が前記通気空間を閉塞するよう構成してもよい。
また、本願発明は、室外のガラリ周辺の水位と連動するフロートをさらに具備し、前記フロートの移動によっても、前記可動羽根による前記通気空間の閉塞を可能に構成してもよい。
また、本願発明は、前記可動羽根による前記通気空間の閉塞後は、水位変動によって前記可動羽根の閉塞が解かれないよう構成してもよい。
また、本願発明は、前記固定羽根および可動羽根のうち少なくとも何れかの羽根において、相対する羽根との接触面に止水ゴムを設けて構成してもよい。 The present invention made in order to solve the above-mentioned problem is a ventilation gully for preventing water from entering at the time of increasing water, having a ventilation space for ventilation, a fixed blade, and a more outdoor side than the fixed blade. A movable blade that is movable to close the ventilation space, and the movable blade closes the ventilation space when the water level around the outdoor gull reaches a predetermined height. It is characterized by the following.
Further, the invention of the present application may be configured such that the movable blade closes the ventilation space by a water pressure of the water received by the movable blade.
In addition, the present invention may further include a float that is linked to a water level around the outdoor slurries, and may be configured so that the movable blade can close the ventilation space by moving the float.
Further, the present invention may be configured such that after the movable blade closes the ventilation space, the closing of the movable blade is not released due to a change in water level.
Further, the present invention may be configured such that at least one of the fixed blade and the movable blade is provided with a waterproof rubber on a contact surface with the opposing blade.

本発明によれば、以下に記載する効果を奏する。
（１）可動羽根が、建物周辺の水位が所定の高さに達した際に自動的に固定羽根にある通気空間を閉塞するように動作するため、建物周辺での洪水などの発生時に、浸水防止機能を確実に発揮することができる。
（２）可動羽根が受ける水の水圧でもって通気空間を閉塞するように動作することで、可動羽根の可動構造をシンプルにすることができる。
（３）室外のガラリ周辺の水位と連動するフロートの移動によって可動羽根が通気空間を閉塞可能に構成することによって、フロートの位置を調整することで、可動羽根が水圧を受け始める前から、可動羽根による通気空間の閉塞動作を開始することができる。
（４）可動羽根による通気空間の閉塞後は、たとえ水位の減少があっても閉塞を維持するよう構成することで、浸水防止の信頼性を高めることができる。
（５）固定羽根と可動羽根との間の接触面に止水ゴムを設けることで、水密性を向上することができる。特に可動バネが受ける水の水圧によって止水ゴムは圧密状態となるため、より止水性の向上に繋がる。 According to the present invention, the following effects can be obtained.
(1) The movable blades automatically operate to close the ventilation space in the fixed blades when the water level around the building reaches a predetermined height. The prevention function can be reliably exhibited.
(2) The movable structure of the movable blade can be simplified by operating to close the ventilation space with the water pressure of the water received by the movable blade.
(3) The movable blade is configured so that the ventilation space can be closed by the movement of the float in association with the water level around the outdoor rag, so that the position of the float is adjusted so that the movable blade is movable before it starts receiving water pressure. The closing operation of the ventilation space by the blade can be started.
(4) After the closing of the ventilation space by the movable blades, even if the water level decreases, the blocking is maintained so that the reliability of the prevention of inundation can be improved.
(5) Watertightness can be improved by providing a waterproof rubber on the contact surface between the fixed blade and the movable blade. In particular, the waterproof rubber is brought into a compacted state by the water pressure of the water received by the movable spring, which leads to further improvement of the waterproofness.

以下、図面を参照しながら、本発明の実施例について説明する。   Hereinafter, embodiments of the present invention will be described with reference to the drawings.

＜１＞全体構成
実施例１に係る換気用ガラリＡ（以下、単に「ガラリ」ともいう。）は、図１に示すように、ガラリの枠体となるフレーム１０の内部に、固定羽根２０および可動羽根３０を少なくとも含んで構成する。
以下、各要素の詳細について説明する。 <1> Overall Configuration As shown in FIG. 1, the ventilation gullies A (hereinafter, also simply referred to as “gullies”) according to the first embodiment include a fixed blade 20 and a fixed blade 20 inside a frame 10 serving as a gully frame. It comprises at least the movable blade 30.
Hereinafter, details of each element will be described.

＜２＞固定羽根
固定羽根２０は、ガラリにおいて換気用の通気空間２１を形成するための部材である。
本実施例において固定羽根２０は、側面視して室外側を短辺側とした略台形状を呈しており、この固定羽根２０を上下方向に所定間隔を設けて配置することで、各固定羽根２０の間に確保された隙間が、室内側と室外側とを通気するための通気空間２１となる。
固定羽根の側端は、フレーム１０の側辺に固定されている。 <2> Fixed Blade The fixed blade 20 is a member for forming a ventilation space 21 for ventilation in a rag.
In the present embodiment, the fixed blades 20 have a substantially trapezoidal shape with the outdoor side as the short side when viewed from the side, and by disposing the fixed blades 20 at predetermined intervals in the vertical direction, each fixed blade The gap secured between the openings 20 serves as a ventilation space 21 for ventilation between the indoor side and the outdoor side.
A side end of the fixed blade is fixed to a side of the frame 10.

＜３＞可動羽根
可動羽根３０は、前記固定羽根２０によって確保されている通気空間２１を閉塞可能とするための部材である。
本実施例において、可動羽根３０は、室内側を短辺側とした略台形状を呈するとともに、前記通気空間２１を閉塞可能な大きさを有しており、固定羽根２０を上下方向に所定間隔を設けて配置することで、各固定羽根２０の間に確保された隙間が、換気用の通気空間２１となる。
可動羽根３０は、前記固定羽根２０よりも室外側に位置しており、固定羽根２０に接近する方向へと移動自在にフレーム１０に取り付けられている。
なお、上下方向に間隔を設けて配置している可動羽根３０は、各自独立して移動自在に構成しても良いし、連動して移動自在に構成しても良い <3> Movable Blade The movable blade 30 is a member capable of closing the ventilation space 21 secured by the fixed blade 20.
In the present embodiment, the movable blade 30 has a substantially trapezoidal shape with the indoor side as the short side, and has a size capable of closing the ventilation space 21. Is provided, the gap secured between the fixed blades 20 becomes the ventilation space 21 for ventilation.
The movable blade 30 is located on the outdoor side of the fixed blade 20 and is attached to the frame 10 so as to be movable in a direction approaching the fixed blade 20.
The movable blades 30 arranged at intervals in the vertical direction may be configured to be movable independently of each other, or may be configured to be movable in conjunction with each other.

＜３．１＞可動羽根の移動機構
可動羽根３０の移動機構は、種々の機構を採用することができる。
図２に、可動羽根３０の移動機構の一例を示す。
図２では、可動羽根３０の両側部に摺動軸を設け、該突起を、ガラリの枠体を構成しているフレーム１０の側辺１１に設けてあるガイド溝１１１に挿通して、このガイド溝１１１内を突起が摺動することで可動羽根３０の移動方向を前後方向（固定羽根２０への接近・離隔方向）に制限する機構などが考えられる。 <3.1> Moving mechanism of movable blade The moving mechanism of the movable blade 30 can employ various mechanisms.
FIG. 2 shows an example of a moving mechanism of the movable blade 30.
In FIG. 2, sliding shafts are provided on both sides of the movable blade 30, and the projections are inserted into guide grooves 111 provided on the side 11 of the frame 10 constituting the frame of the gull, and this guide is provided. A mechanism that limits the moving direction of the movable blade 30 in the front-rear direction (the direction of approaching / separating from the fixed blade 20) by sliding the protrusion in the groove 111 is conceivable.

＜３．２＞ガイド溝の形状
ガイド溝１１１の形状は、可動羽根３０による通気空間２１の閉塞動作に支障が無い範囲で、任意の形状（直線状、湾曲状、鉤状など）を採用することができる。
このガイド溝１１１の形状でもって、一旦通気空間２１を閉塞した後の水位減少によって可動羽根３０が自動的に初期位置に戻るか否かを設定することができる。
図２では、ガイド溝１１１の形状は、前後方向を長手方向とする直線状を呈している。この形状を採用する場合、一旦通気空間２１を閉塞した後の水位減少によって可動羽根３０が自動的に初期位置へと戻らない作用を期待している。 <3.2> Shape of Guide Groove As the shape of the guide groove 111, an arbitrary shape (such as a linear shape, a curved shape, and a hook shape) is employed as long as the movable blade 30 does not interfere with the closing operation of the ventilation space 21. be able to.
With the shape of the guide groove 111, it is possible to set whether or not the movable blade 30 automatically returns to the initial position due to a decrease in the water level after the ventilation space 21 is once closed.
In FIG. 2, the shape of the guide groove 111 has a linear shape whose longitudinal direction is the front-rear direction. In the case of adopting this shape, it is expected that the movable blade 30 does not automatically return to the initial position due to a decrease in the water level after the ventilation space 21 is once closed.

＜４＞増水時の動作
図１（ｂ）に示すように、洪水等の増水によって建物の周辺の水位がガラリにまで達すると、増水した水の水圧を可動羽根３０の前面側で受けることとなる。この水圧でもって可動羽根３０が固定羽根２０側に後退し、通気空間２１は可動羽根３０によって閉塞されるため、ガラリを通じて浸水することが無くなる。 <4> Operation at the time of increasing water As shown in FIG. 1 (b), when the water level around the building reaches the level of water due to flooding or the like, the water pressure of the increased water is received on the front side of the movable blade 30. Become. With this water pressure, the movable blade 30 retreats to the fixed blade 20 side, and the ventilation space 21 is closed by the movable blade 30, so that water is not flooded through the rattle.

＜５＞増水収束後の動作
増水が収束し、ガラリ周辺の水位が減少してきた場合、一度通気空間２１を可動羽根３０で閉塞した後は、可動羽根３０の受ける水圧が減少したとしても、ガイド溝１１１による可動羽根３０の移動軌跡は前後方向（水平方向）であるため、可動羽根３０が自動的に初期位置に戻ることは無い。
よって、人力等で可動羽根３０を引き戻すなどの作業を行えば、可動羽根３０を初期位置に戻し、通気空間２１を再度確保した状態に戻すことができる。 <5> Operation after Convergence of Water Increasing When the water converges and the water level around the gull is decreasing, once the ventilation space 21 is closed by the movable blade 30, even if the water pressure received by the movable blade 30 decreases, the guide does not work. Since the moving trajectory of the movable blade 30 by the groove 111 is in the front-rear direction (horizontal direction), the movable blade 30 does not automatically return to the initial position.
Therefore, if work such as pulling back the movable blade 30 by human power or the like is performed, the movable blade 30 can be returned to the initial position, and the state can be returned to the state where the ventilation space 21 is secured again.

なお、図示しないが、可動羽根３０を弾性体などによって初期位置側に付勢した状態とすれば、増水の収束後に可動羽根３０が自動的に初期位置に復元する作用も期待できる。ただし、弾性体による付勢が、水圧による可動羽根３０の後退動作の妨げにならない程度とする必要がある。   Although not shown, if the movable blade 30 is urged toward the initial position by an elastic body or the like, an effect of automatically restoring the movable blade 30 to the initial position after the convergence of the increased water can be expected. However, it is necessary that the urging by the elastic body does not hinder the retreat operation of the movable blade 30 due to the water pressure.

＜１＞全体構成
実施例２に係る換気用ガラリについて図３を参照しながら説明する。
実施例１に係る換気用ガラリとの相違点は、可動羽根３０を、フロート５０の移動によっても移動可能に構成している点である。
フレーム１０の下方に雨水ます４０を設けておき、この雨水ます４０にフロート５０を配置する。さらにフロート５０には上方に伸びる連結材５１を設けておき、この連結材５１に各可動羽根３０を連結している。
また、可動羽根３０の両側端および、フレーム１０の側辺１１には可動羽根３０の移動方向を制限するための軸部３１およびガイド溝１１１を設けている。
このガイド溝１１１は、通常時から増水時に向かって可動羽根３０が上方向にも移動するよう、湾曲軌跡を呈している。そのため、可動羽根３０は、通常時から増水時に遷移する際、斜め上方向に移動するように配置されている。 <1> Overall Configuration A ventilation galley according to the second embodiment will be described with reference to FIG.
The difference from the ventilation louver according to the first embodiment is that the movable blade 30 is configured to be movable by the movement of the float 50.
A rain basin 40 is provided below the frame 10, and a float 50 is arranged on the rain basin 40. Further, a connecting member 51 extending upward is provided on the float 50, and each movable blade 30 is connected to the connecting member 51.
Further, a shaft portion 31 and a guide groove 111 for restricting the moving direction of the movable blade 30 are provided on both side ends of the movable blade 30 and the side edges 11 of the frame 10.
The guide groove 111 has a curved trajectory so that the movable blade 30 also moves upward from the normal time to the time of increasing water. Therefore, the movable blade 30 is arranged so as to move diagonally upward when transitioning from normal time to water increase.

＜２＞増水時の動作
図３（ｂ）に示すように、洪水等の増水によって建物の周辺の水位が上昇すると、雨水ます４０に水が流れ込み、フロート５０は浮力で浮上する。
このフロート５０の浮上と連動して、可動羽根３０は固定羽根２０の間の通気空間２１を閉塞するように移動する。
よって、本実施例に係る構成によれば、可動羽根３０が水圧を受けることのできる高さにまで増水の水位が及んでいない場合であっても、フロート５０を上昇できる高さにまで水位が上昇した段階から可動羽根３０による通気空間２１の閉塞作業を開始することができる。
なお、水位の上昇が進み、可動羽根３０が水圧を受ける段階に達した場合には、実施例１に係る構造と同様に、水圧でもって可動羽根３０が固定羽根２０側に押し込まれてより水密性を高めるように作用する。 <2> Operation at the time of rising water As shown in FIG. 3B, when the water level around the building rises due to the rising water such as a flood, the water flows into the rain water basin 40, and the float 50 floats by buoyancy.
In conjunction with the floating of the float 50, the movable blade 30 moves so as to close the ventilation space 21 between the fixed blades 20.
Therefore, according to the configuration according to the present embodiment, even when the rising water level does not reach the height at which the movable blade 30 can receive the water pressure, the water level rises to the height at which the float 50 can rise. The work of closing the ventilation space 21 by the movable blade 30 can be started from the raised stage.
When the water level rises and reaches a stage where the movable blade 30 receives the water pressure, similarly to the structure according to the first embodiment, the movable blade 30 is pushed into the fixed blade 20 side by the water pressure and becomes more watertight. Acts to enhance the sex.

＜３＞増水収束後の動作
増水が収束し水位が引いてくると、可動羽根３０は水圧を受けなくなるものの、雨水ます４０に水が残っている限りフロート５０は浮上し続けるため、通気空間２１の閉塞は維持される。
なお、雨水ます４０にも水が残らない場合には、フロート５０は下降し、可動羽根３０は元の位置へも戻るため、再度通気空間２１が確保される。
上記した増水収束後の動作は、所望に応じて任意に設計すればよい。 <3> Operation after Convergence of Water Increasing When the water converges and the water level decreases, the movable blade 30 stops receiving the water pressure, but the float 50 continues to float as long as the water remains in the rainwater basin 40. Blockage is maintained.
If no water remains in the rainwater basin 40, the float 50 descends and the movable blade 30 returns to its original position, so that the ventilation space 21 is secured again.
The operation after the above convergence of the water increase may be arbitrarily designed as desired.

実施例３に係る換気用ガラリについて図４を参照しながら説明する。
本実施例に係る換気用ガラリは、固定羽根２０や可動羽根３０に止水ゴム６０を設けてもよい。
以下、止水ゴム６０の配置例について説明する。 Third Embodiment A ventilation gallery according to a third embodiment will be described with reference to FIG.
In the ventilation loudspeaker according to the present embodiment, the stationary blade 20 and the movable blade 30 may be provided with a waterproof rubber 60.
Hereinafter, an example of the arrangement of the waterproof rubber 60 will be described.

＜１＞対向する羽根との間の接触面に止水ゴムを設けた構成（図４（ａ））
図４（ａ）は、固定羽根２０と可動羽根３０との接触面を示す側端面図であり、固定羽根２０および可動羽根３０の両方に、対向する羽根との間の接触面に、止水ゴム６０を設けた構成を示している。
この止水ゴム６０は水圧を受けた可動羽根３０の移動に伴って互いに圧縮する方向に作用するため、水密性をより高めることができる。 <1> Configuration in which waterproof rubber is provided on the contact surface between the opposing blades (FIG. 4A)
FIG. 4A is a side end view showing a contact surface between the fixed blade 20 and the movable blade 30. Both the fixed blade 20 and the movable blade 30 have a water stoppage on the contact surface between the opposed blades. The configuration in which the rubber 60 is provided is shown.
The water-stop rubbers 60 act in a direction of compressing each other with the movement of the movable blades 30 that have received the water pressure, so that the watertightness can be further improved.

＜２＞可動羽根の側端に止水ゴムを設けた構成（図４（ｂ））
図４（ｂ）は、フレーム１０と可動羽根３０との接触部周辺を示す概略斜視図であり、可動羽根３０においてフレーム１０との接触面である側端に止水ゴム６０を設けた構成を示している。
この止水ゴム６０は水圧を受けた可動羽根３０の移動に伴ってフレーム１０との間で圧縮する方向に作用するため、水密性をより高めることができる。
なお、この止水ゴム６０の表面や、フレーム１０の側辺１１の内側には、可動羽根３０の移動を円滑にすべくテーパを設けておいても良い。 <2> Configuration in which waterproof rubber is provided at the side end of the movable blade (FIG. 4B)
FIG. 4B is a schematic perspective view showing the vicinity of a contact portion between the frame 10 and the movable blade 30. FIG. 4B shows a configuration in which a waterproof rubber 60 is provided on a side end of the movable blade 30 that is a contact surface with the frame 10. Is shown.
The water-stop rubber 60 acts in a direction of compressing with the frame 10 with the movement of the movable blade 30 which receives the water pressure, so that the watertightness can be further improved.
A taper may be provided on the surface of the water-stop rubber 60 or inside the side edge 11 of the frame 10 in order to smoothly move the movable blade 30.
